Bill gates - We're not ready

Bill Gates had a clear future vision in 2015 but I guess nobody listened to him.

In 2014, the world avoided a global outbreak of Ebola, thanks to thousands of selfless health workers -- plus, frankly, some very good luck. In hindsight, we know what we should have done better. So, now's the time, Bill Gates suggests, to put all our good ideas into practice, from scenario planning to vaccine research to health worker training. As he says, "There's no need to panic ... but we need to get going."
But now in 2020 We still not ready!
When I watched this video I really wonder why we're not ready? 6 years gone after Ebola crisis and we still use the same ways in 2020 with coronavirus crisis.
